本文介绍了一个iOS应用中使用五个不同的UINavigationController实例配合UITabBarController实现底部标签栏导航的初始化过程。具体包括了如何创建并配置每个导航控制器及其对应的根视图控制器，并将它们整合到UITabBarController中。

@interface __2AppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
UINavigationController *navController1;
UINavigationController *navController2;
UINavigationController *navController3;
UINavigationController *navController4;
UINavigationController *navController5;
UISegmentedControl *segmentedController;
UITabBarController *tabBarController;
}
 
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic,retain) IBOutlet UINavigationController *navController1;
@property (nonatomic,retain) IBOutlet UINavigationController *navController2;
@property (nonatomic,retain) IBOutlet UINavigationController *navController3;
@property (nonatomic,retain) IBOutlet UINavigationController *navController4;
@property (nonatomic,retain) IBOutlet UINavigationController *navController5;
@property (nonatomic,retain) IBOutlet UISegmentedControl *segmentedController;
@property (nonatomic,retain) IBOutlet UITabBarController *tabBarController;

 
@end


@synthesize window;
@synthesize navController1;
@synthesize navController2;
@synthesize navController3;
@synthesize navController4;
@synthesize navController5;
@synthesize segmentedController;
@synthesize tabBarController;
